I think the opposite is true in many cases, like why we lost the "Cuban vote" in Florida this year. The first generation of immigrants really did believe in traditional family values and despised socialism after they escaped a communist hell hole. But the third generation Cuban Americans don't care about grandpa's life and think socialism is kewl and gay marriage is hip.
you are not correct in what you write - the Cuban exile community is not made up of descendants from a static event three generations ago - there have been successive waves of Cuban refugees - the first one from 1959-1962 (who had almost no eperience living under communism); the influx from the early 1970s; the arrivals from the Mariel boatlift in 1980; a new wave from 1990-1993; and a constant stream since 2000. Each of these waves had entire families with people of all ages - you could find an 80 year old who came in 1960, and another 80 year old who came here last month. There are teenagers who don’t even speak Spanish, and other teenagers who are recent arrivals who don’t speak English - and everything in between.
